Sharka caused by Plum pox virus (PPV) is the most harmful disease of stone fruits in Europe and elsewhere in the world. There is no highly PPV resistant cultivar of plum. Biotech approach has led to the development of resistance through genetic engineering. In this study, we evaluated a transgenic plum Prunus domestica L., clone C5 (cv. HoneySweet), where the PPV resistance is based on RNA interference...
The Cydia pomonella granulovirus (CpGV) is an important agent for control of the codling moth C. pomonella (L.). Since 2004, cases of resistance to CpGV products have been found in codling moth populations of several apple plantations in Europe. Recently, the first codling moth population (Cp-VBII) with reduced susceptibility to CpGV was found in the Czech Republic. The F1 offspring of Cp-VBII collected...
Apple stem pitting virus (ASPV) is a causal agent of stem pitting associated disease in pomes fruit trees. The present report focuses on a cytopathological effect of ASPV infection in a herbaceous host Nicotiana occidentalis ‘37B’. A leaf dip preparation shows predominantly basic virus particles and aggregated particles 800 nm and 3200 nm long respectively. The main cytopathological effect observed...
